A binary salt...

Question

A binary salt (X) of alkali metal on heating with sulphur give (Y); (Y) with $B a C l_{2}$ solution gave white ppt.
(Z) is insoluble in conc $H C l$ . 14.2 g of (X) gave 23.3 g of (Z). Identify (X), (Y) and (Z) and explain reactions.

Solution

$2 K O_{2} (x) + S ⟶ K_{2} S O_{4} (y) + B a C l ⟶ B a S O_{4} (z)$
$2 \times 71 ℊ 233 ℊ$
$∵ 142 ℊ K O_{2}$ give $233 ℊ$ of $B a S O_{4}$
$14.2 ℊ$ of $K O_{2}$ gives $23.3 ℊ$ of $B a S O_{4}$
